“…They have been reported to occur after procedures such as percutaneous nephrostomy, stone basketing, cystoscopy, and extracorporeal shock wave lithotripsy. [73][74][75] As minimally invasive procedures become more invasive, it is possible that urinomas may be seen more frequently. In one study, urinomas were reported in 3 out of 16 ablation-assisted laparoscopic partial nephrectomies.…”

Renal cysts are a common imaging finding. Although most cysts never have symptoms, some cause pain, collecting system compression, hematuria, hypertension, and secondary infection. The mere presence of a cyst is not an indication for intervention, but treatment may be indicated in symptomatic patients or those with secondary obstruction. Urinomas generally are a contained collection of urine outside of the normal pathways where urine travels. As such, urinomas can arise anywhere from the upper abdomen down into the low pelvis and have a variety of etiologies. Ureteral obstruction with forniceal rupture and trauma (blunt, penetrating, or iatrogenic) are the most common causes of urinomas. When urinomas arise spontaneously, the likely cause varies with the patient's age. Blunt or penetrating trauma can cause perinephric urinomas by two mechanisms-direct disruption of the pelvis or collecting system or by degeneration of nonviable tissue. These urinomas are often perinephric, but can also occur in a subcapsular location. This review will discuss diagnosis, classification, and treatment of renal cysts and urinomas.

“…A pelvic mass due to recurrent rectal carcinoma caused bilateral ureteral obstruction, which was confirmed by intravenous pyelogram (Fig 3). DISCUSSION Urinoma formation as a complication of percutaneous nephrostomy is uncommon, but it has been reported frequently after other traumatic injuries [5] (Table I).

“…Only 8 cases secondary to tumor have been reported, probably because tumors usually cause a more chronic form of obstruction than stones or most other benign conditions [3,4]. Urinoma formation as a complication of nephrostomy tube insertion has also been reported but is rare since the extravasate usually drains around the nephrostomy catheter [5]. When deterioration of renal function results from chronic ureteral obstruction, the utilization of diagnostic procedures is limited, because contrast material cannot be used in the face of a high blood urea nitrogen and creatinine.…”
